Question 1

A resting state has a negative charge of about 200 millivolts.

Accepted Answer

Resting states have negative electrical charges of about -70 millivolts.

Question 2

Excitatory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire.

Accepted Answer

Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire.

Question 3

A portion of the brain known as the central core is quite similar in all vertebrates.

Accepted Answer

The central core is very much the same in all vertebrates.

Question 4

Neurons have a cell body and a nucleus as well as dendrites and axons.

Accepted Answer

Neurons have a cell body and nucleus,like most types of cells in the body.They also have dendrites and axons that perform actions within the body.

Question 5

The basic elements of the nervous system are known as ____________.
A)axons
B)neurons.
C)dendrites
D)stimuli

Accepted Answer

Neurons are the basic elements of the nervous system and are involved in the control of behavior.

Question 6

Neurons fire,transmit an electrical impulse along the axon,or don't fire.

Accepted Answer

Neurons either fire or don't fire.That is the whole point of what neurons do within the structure.

Question 7

The autonomic division of the peripheral nervous system can be broken down into three smaller divisions called the sympathetic,the parasympathetic,and the neural.

Accepted Answer

There are two smaller divisions of the PNS,the sympathetic and the parasympathetic.

Question 8

The cortex has three major sections called lobes.

Accepted Answer

The cortex has four major sections called lobes.

Question 9

Terminal buttons are chemicals that carry messages across the synapse to a dendrite of a receiving neuron.

Accepted Answer

Neurotransmitters are chemicals that carry messages across the synapse to a dendrite (and sometimes cell body)of a receiving neuron.

Question 10

The central core is sometimes referred to as the "old brain" because its evolution can be traced back some 500 million years to primitive structures found in nonhuman species.

Accepted Answer

The central core is definitely called the old brain and can be traced back 500 million years.

Question 11

Drugs that trigger the development of new neurons might be used to counter diseases like Alzheimer's that are produced when neurons die.

Accepted Answer

Research shows that drugs that trigger the development of new neurons are being used to treat Alzheimer's disease.

Question 12

Duplicate neurons fire not only when a person enacts a particular behavior,but also when a person observes another individual carrying out the same behavior.

Accepted Answer

Mirror neurons have been identified within the last decade and show that people fire when they are observing others carrying out a behavior.

Question 13

The cerebral cortex is responsible for our ability to think,evaluate,and make complex judgments.

Accepted Answer

The cerebral cortex is directly responsible for thinking,evaluation,and making complex judgments.

Question 14

There are two major divisions of the peripheral nervous system.

Accepted Answer

The two major divisions of the peripheral nervous system are the somatic and autonomic divisions.

Question 15

Each kind of neurotransmitter is exactly the same as the others.

Accepted Answer

Each kind of neurotransmitter is unique and has a distinctive configuration that allows it to fit into a specific type of receptor cell.

Question 16

The brain controls our behavior during every waking and sleeping moment.

Accepted Answer

The brain is responsible for all of our actions and reactions.

Question 17

Inhibitory messages make it more likely that a receiving neuron will fire and an action potential will travel down its axon.

Accepted Answer

Excitatory messages are one of the two types of chemical messages that a neurotransmitter emits if it fits into a site on the receiving neuron.They make it more likely that a receiving neuron will fire and action potential will travel down its axon.

Question 18

Excitatory messages make it more likely that a receiving neuron will fire and an action potential will travel down its axon.

Accepted Answer

Excitatory messages are one of the two types of chemical messages that a neurotransmitter emits if it fits into a site on the receiving neuron.They make it more likely that a receiving neuron will fire and action potential will travel down its axon.

Question 19

The pituitary gland is known as the master gland because it controls the functioning of the rest of the endocrine system.

Accepted Answer

The pituitary gland is known as the master gland.It does control the functioning of the endocrine system.It also affects emotional reactions,sexual urges,and energy levels.

Question 20

Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire.

Accepted Answer

Inhibitory messages provide chemical information that prevents or decreases the likelihood that the receiving neuron will fire.
